G125-FS12605F1R

Overview

The Harwin G125-FS12605F1R is a Gecko-SL series power-to-board female receptacle connector designed for surface mount technology. It features a double-row configuration with 26 positions (13+13) and a 1.25 mm pitch. The component supports a current rating of 2 A and voltage ratings of 250 V or 450 V. Constructed with gold-plated copper alloy contacts, it ensures reliable performance in high-vibration environments through a patented four-finger contact design. The housing is made of green nylon, operating within a temperature range of -65°C to +150°C. Packaged in tape and reel format with pick-and-place caps, it facilitates automated assembly.

Feature Summary

• Patented four-finger contact design maintains electrical connection under high vibration and shock conditions
• Integrated polarizing key prevents incorrect mating orientation
• Surface mount vertical form factor optimized for automated pick-and-place manufacturing processes

Applications

• General purpose electronic interconnects requiring high reliability
• Industrial equipment subject to mechanical stress and vibration
• Automotive electronics demanding robust power connections

Procurement Notes

Verify the specific datasheet version to confirm whether the voltage rating is specified as 250 V or 450 V, as documentation varies. Ensure the procurement order includes the necessary pick-and-place caps if automated surface mounting is required. Confirm RoHS compliance status directly with the manufacturer's latest environmental declarations before finalizing supply chain agreements.

Selection Notes

Select this component when a vertical surface mount female connector is required for space-constrained designs. The 1.25 mm pitch allows for dense pin arrangements while maintaining adequate spacing. Consider the 26-position capacity for applications needing multiple power or signal lines. The straight vertical profile suits boards where height clearance is limited but board penetration is not desired.

Part Context

This part belongs to the Harwin Gecko-SL family, which specializes in high-reliability connectors for harsh environments. The series utilizes proprietary contact engineering to ensure durability against shock and vibration. As a power-to-board solution, it bridges PCB-mounted components with external systems, offering a compact alternative to traditional through-hole headers in modern electronics manufacturing.

Replacement Considerations

No public confirmed substitute part numbers are available for this specific model. Due to the unique patented four-finger contact geometry and specific housing dimensions, direct replacements may require re-verification of mechanical fit and electrical characteristics.
